Review on 🔑 KeylessOption Keyless Entry Remote Fob Car Flip Ignition Key Replacement for Chevy Trailblazer GMC Envoy (Pack of 2) by Mark Walsh

This item was advertised to work with MYT3X6898B compatible systems. I have attached a picture of my keychain with the same number which works great. After cutting out these keys I tried to program them on my truck. I followed the procedure and was able to program it with my key fob that I had before ordering. It correctly responds to the radio signal sent by my work and my key fob. However, he does not respond to either of these two keychains that I ordered from you. I checked the voltage on the batteries in both new key fobs and both came out at 3v as expected. Key fobs work fine just not with my car as per your description. So a star.
